Tangle Formation Involving Hair Fibers Looped over Other Hairs and Severe Bending Deformations

چکیده
Literature dealing with the mechanisms of hair breakage in combing and brushing published so far has been reviewed as a background for the critical evaluation of the method and data analysis of the paper “Statistical Analysis of Hair Breakage. II” by Evans and Park (1). Accumulated knowledge about hair breakage in these grooming processes indicates that hair breakage in combing and brushing results from tangling, looping, knotting, and impact loading. Fatiguing, though responsible for some weakening of the fi ber in the grooming process, it is unlikely to be a signifi cant factor in hair breakage in combing and brushing.

Circle Hairs Involving the Extremities in a Young Girl
Circle hairs (CHs) represent a body hair growth disorder which is characterized by asymptomatic presence of hairs in typical circular or spiraliform arrangement. It is not associated with follicular or inflammatory abnormalities. CHs are rarely reported, probably underestimated, as medical consultation for CH only is rare in practice. It needs to be differentiated from rolled hairs, which is a ...
متن کاملDiscreet Monilethrix: De novo Mutation on the Example of Polish Families
Trichoscopy examination revealed the presence of few empty follicles, small broken hairs, black dots, and hair with uniform nodal dilatations with intermittent constrictions at which there was shaft breakage [Figure 2]. The hairs were of varying lengths; many were broken. Hairs with normal morphology were seen interspersed within this beaded hair. The beaded hair showed bending in different dir...
متن کاملThe Arabidopsis Rop2 GTPase is a positive regulator of both root hair initiation and tip growth.
Root hairs provide a model system for the study of cell polarity. We examined the possibility that one or more members of the distinct plant subfamily of RHO monomeric GTPases, termed Rop, may function as molecular switches regulating root hair growth. Specific Rops are known to control polar growth in pollen tubes. Overexpressing Rop2 (Rop2 OX) resulted in a strong root hair phenotype, whereas...
متن کاملA common origin of voltage noise and generator potentials in statocyst hair cells
Voltage noise, generator potentials, and hair movements in the Hermissenda statocyst were analyzed. Motile hairs on the cyst's luminal surface moved as rods through +/- 10 degrees Hz when free and at 7 Hz when loaded with the weight of the statoconia (at 120 degrees C). For hair cells oriented opposite to a centrifugal force vector, rotation caused depolarization and increase of voltage noise v...
متن کاملExamination, Analysis, and Application of Hair in Forensic Science - Animal Hair.
This article reviews the examination of animal hairs and their role in the forensic arena. The forensic examination of animal hair is a well-established discipline and has been so for two centuries. Examination is largely based on microscopy, which may enable the hair analyst to identify a hair as animal in origin, to characterize the hair to a particular species, and to conduct comparative exa...
